Seadek Installation Guide: Aluminum Boat Edition

SeaDek is a brand of high-quality marine flooring and decking material. It is a durable, non-skid surface that can significantly enhance your boating experience, comfort, safety, and aesthetics. SeaDek is easy to install and can be done without a professional. The process involves determining the deck areas and their measurements, getting a quote from a provider, preparing the materials needed, preparing the surface, fitting the SeaDek and making adjustments, applying the SeaDek pieces, and giving the deck flooring time to cure. The installation process is simple and can be completed by following the provided instructions and taking the necessary precautions.

Surface preparation

Before installing SeaDek on your aluminium boat, it is important to prepare the surface thoroughly. SeaDek uses 3M pressure-sensitive peel-and-stick adhesive, so to ensure proper bonding, the deck must be cleaned of any dirt, oil, wax, or other contaminants.

Firstly, scrub the deck with a stiff-bristle brush and soap and water. Rinse the deck thoroughly, and dry it with a towel to eliminate water spots. Then, wipe down each section of the deck with denatured alcohol or acetone, using a clean, lint-free cloth. This will ensure the surface is free from any remaining dirt, wax, or residue.

Wait until the surface is completely dry before proceeding to the next step. It is important to note that SeaDek should not be installed in temperatures below 50 degrees Fahrenheit.

Choosing the right SeaDek

Secondly, SeaDek is available in a wide range of colours, patterns, and textures, allowing you to customise the look and feel of your boat. You can select from contemporary designs like embossed dots or choose a brushed texture for a classic teak appearance. It is recommended to opt for lighter, cooler colours like white, beach sand, or cool grey for the top layer to avoid overheating on sunny days.

Thirdly, consider the functionality and comfort SeaDek provides. It offers excellent traction, cushioning for your feet, and reduces reflected glare. This makes it ideal for fishing boats, runabouts, and watersports boats.

Finally, if you feel unsure about creating templates and installing SeaDek yourself, you can always seek assistance from a SeaDek-certified fabricator. They can help you refine your design, ensure proper installation, and provide guidance on positioning and maintenance.

By following these steps and considering your personal preferences, you can choose the right SeaDek to enhance the appearance, comfort, and functionality of your aluminium boat.

Measuring and cutting

To begin, you will need to determine the deck areas you want to cover and take accurate measurements for each section. It is recommended to allow for a bit of excess material to account for any mistakes and to have extra for boat accessories. Before cutting, gather the necessary tools, including a straightedge or ruler, and a sharp utility or razor knife.

When you are ready to cut, start by arranging the SeaDek pads to best fit the area. Do not remove the adhesive backing at this stage. Sketch the shape and placement of the pads on paper, marking the measurements for cutting. Remember to measure twice and cut once to ensure accuracy. Cut each pad before applying it to your boat, using a sharp razor knife guided by a straight edge for straight cuts, and a curved template for the corners. Always use a backing, such as plywood, when cutting the SeaDek material—never cut directly on your boat.

Once you have cut the pads, you can arrange them in their proper positions and make any necessary adjustments. Mark the positions with a pencil to ensure proper placement.

Sticking the SeaDek

Now that you've prepared the surface, it's time to stick the SeaDek pieces in place. Before installing the piece, check if the SeaDek pieces fit correctly and align with the contours of the surface. Don't remove the adhesive backing just yet. For proper alignment, measure and mark the boat's centerline with a pencil or marker. Also, mark the areas that need adjustment.

When you're ready, take the corner of the SeaDek piece and peel off a small section of the adhesive backing. Press it down onto the surface, aligning it with the marked centerline. Slowly peel off the rest of the backing and apply pressure to stick it to the surface. Repeat this process for each SeaDek piece, taking it one section at a time. After applying each piece, smooth out any air bubbles and wrinkles using a clean, lint-free rag. Push the trapped air from the centre outward. If there are stubborn bubbles, a heat gun may be necessary. You only need the low setting to make the pieces more pliable and easy to work with.

Once all the pieces are in place, firmly press down on all surface areas and edges to ensure uniform adhesion. Remember, SeaDek should not be installed in temperatures below 50 degrees Fahrenheit.

After installation, allow the SeaDek to cure for the recommended amount of time. Keep it away from water or extreme conditions during this period. Refer to the installation instructions provided by SeaDek for your specific kit, as there may be variations.

Aftercare and maintenance

SeaDek is designed to be durable and long-lasting, but proper aftercare and maintenance are essential to preserving its quality and appearance. Here are some detailed instructions to help you maintain your SeaDek installation:

Cleaning

Clean your SeaDek regularly with fresh water, mild soap, and a medium-bristle brush. This will help remove dirt, grime, and any residue that may build up over time. For stubborn stains or spots, such as dried fish blood, you can use a small, stiff-bristle brush and ammonia or a pressure washer on a light nozzle setting. It is recommended to use Dek Magic, SeaDek's branded cleaner, specifically formulated for PE/EVA foam. Alternatively, you can use soap, hot water, and a stiff brush. Avoid using acid-based cleaners, as these may damage the material.

Protecting the Surface

Keep the boat covered when not in use to shield the SeaDek from prolonged exposure to the elements, including direct sunlight, which can cause discolouration and fading. Avoid dropping sharp objects on the SeaDek, as the EVA foam material can be punctured or torn. Be cautious when using a high-pressure water hose near the edges, as the force of the water can lift them.

Stain Removal

While SeaDek is highly stain-resistant, some substances, such as fuel stabilizers, bird droppings, rust, and mustard, can cause stains if not addressed promptly. It is important to clean any spills or stains as soon as possible to ensure easy removal.

Adhesive Maintenance

If you notice any issues with the adhesive, such as peeling or lifting corners, you can use a small amount of acetone to help re-adhere the SeaDek to the surface. Apply acetone to the affected area and use a putty knife to lift and re-adhere the corner.

Replacing Panels

SeaDek panels typically have a lifespan of around 10 years with proper care. However, if you need to replace them sooner due to damage or wear, you can order replacement panels from a SeaDek fabricator or directly from SeaDek. Since your original templates are kept on file, replacing the panels is a relatively easy and affordable process.

By following these aftercare and maintenance instructions, you can ensure that your SeaDek installation remains in good condition and provides a safe and aesthetically pleasing surface for your boat.
